Creating and editing protocol-level HTTP settings

Purpose:

HTTP settings determine the parameters of the connection on the protocol level, including timeout value, and so on. Complete the following procedure to create a new HTTP settings profile or edit an existing one.

Caution:

Modifying the HTTP settings is recommended only to advanced users. Do not modify these settings unless you exactly know what you are doing.

Steps:
  1. Navigate to the Settings tab of the HTTP Control menu item and click to create a HTTP setting profile. Enter a name for the profile (for example http_special).

  2. Click to display the parameters of the connection.

  3. Modify the parameters as needed. The following parameters are available:

    • Idle timeout: Timeout value for the session in milliseconds. To avoid early timeout, set it to a larger value, for example a week (604800000 milliseconds).

      Caution:

      Determining if a connection is idle is based on the network traffic generated by the connection, not the activity of the user. For example, if an application or the taskbar of a graphical desktop displays the time which is updated every minute, it generates network traffic every minute, negating the effects of timeout values greater than one minute and preventing SPS from closing the connection.

    • Session timeout: Timeout value for the session in seconds.

    • Enable pre channel check: Select this option to evaluate the connection and channel policies before establishing the server-side connection. That way if the connection is not permitted at all, SPS does not establish the server-side connection.

      NOTE:

      This option cannot be disabled.

  4. Click Commit.

  5. Select this settings profile in the HTTP settings field of your connections.

ICA-specific settings

The following sections describe configuration settings available only for the ICA protocol. Use the following policies to control who, when, and how can access the ICA connection.

NOTE:

As an experimental feature, IPv6 addresses can be configured for ICA connections.

Setting up ICA connections

This section focuses on describing the ICA-specific details of connection configuration. For a detailed description on configuring connections, see General connection settings.

Caution:

If the clients are accessing a remote application or desktop that is shared for Anonymous users (that is, the Users properties of the application is set to Allow anonymous users in the Citrix Delivery Services Console), the actual remote session will be running under an Anonymous account name (for example, Anon001, Anon002, and so on), not under the username used to access the remote server. Therefore, you need to enable usermapping to the Anon* usernames.

To accomplish this, create a usermapping policy and set the Username on the server option to Anon*, and the Groups option to *, then use this usermapping policy in your ICA connections. For details on using usermapping policies, see Configuring usermapping policies.

Reliable connection is also known as Common Gateway Protocol (CGP). It attempts to reconnect to the server in case of a network failure. To use this feature, enable Reliable and enter the default port in the Port field in the upper right corner.

Enable Act as SOCKS proxy to configure the client to use SPS as a SOCKS proxy. If you have enabled this option, you can select Inband destination selection as Target. Enter the IP address or the IP address/Prefix of the brokers (Citrix XML Brokers) used by the client in this connection policy into the Address field. It is also recommended to enable access to the brokers on port 443, as the clients usually try to access the broker using this port first. Disabling port 443 will cause a denied connection to appear on the SPS Search interface for every connection attempt (but the clients will be able to connect the server).

Caution:

SPS does not audit or monitor the traffic between the brokers and the clients in any way, and are not listed on the SPS search interface. Only the connections between the clients and the actual servers are audited.

Caution:

If SPS is acting as a SOCKS proxy and a client attempts to access a server that it is not permitted to access according to the configuration of SPS, SPS will deny the connection. However, the Citrix client application will automatically attempt to connect the server directly without using a proxy and will succeed if the server is directly accessible from the client. Ensure that your firewalls are configured properly to prevent such connections, as these direct connections cannot be audited by SPS.

NOTE:

When enabling Reliable connection or Act as SOCKS proxy the first time, a warning is displayed suggesting the default port to be used based on the specific settings. Also, read the tooltips on these options as they contain up-to-date information about the default port numbers.

Supported ICA channel types

The available ICA channel types and their functionalities are described below. For a list of supported client applications, see Supported protocols and client applications.

  • Drawing (Thinwire): Enables access to the server's desktop (screen). This channel is for remoting graphics and user input (keyboard, mouse). This channel must be enabled for ICA to work.

  • Audio Mapping: Enable access to the sound device of the server.

  • Drive Mapping: Enable access to the client's hard drives on the server.

  • Clipboard: Enable access to the server's clipboard: the clipboard of the remote desktop can be pasted into local applications (and vice-versa). Note that SPS can audit the clipboard channel, but the Safeguard Desktop Player currently cannot search or display its contents.

  • Smartcard: Enable using client side installed smartcards in server-side applications.

  • Printer (COM1): Enable access to the serial port COM1.

  • Printer (COM2): Enable access to the serial port COM2.

  • Printer (LPT1): Enable access to the parallel port LPT1.

  • Printer (LPT2): Enable access to the parallel port LPT2.

  • Printer Spooler: Enable access to the client's printer from the remote desktops and applications.

  • HDX Mediastream: Some user widgets (for example Flash player) will not run on the server but on the client. These widgets are controlled from the server side using this channel. This is not supported by Safeguard Desktop Player and it is disabled by default.

  • USB: Enable using client side installed USB devices in server-side applications.

  • Seamless: Enable seamless channels that run a single application on the ICA server, instead of accessing the entire desktop. When disabled, the application window will be accessed along with an empty desktop.

  • Speedbrowse: Speeds up web browsing. Not currently supported by Safeguard Desktop Player, should be disabled by default.

  • Custom: Applications can open custom channels to the clients connecting remotely to the server. Enabling the Custom channel allows the clients to access all of these custom channels. To permit only specific channels, enter the unique names of the channel into the Details field.

NOTE:

When the channel opens, there are certain cases when the remote group is not known yet. For example, in case of an RDP or ICA login screen, the drawing channel has to be opened first to properly display the logon screen. Only those channel rules will apply, where the Remote group field is empty. In case of network level authentication, all required information is present already so this limitation does not apply.

NOTE:

Multi-stream ICA is not supported in SPS 5 F9.
